Detailed Description▲
A Qt3DRender::QGeometry class is used to group a list of Qt3DRender::QAttribute objects together to form a geometric shape Qt3D is able to render using Qt3DRender::QGeometryRenderer. Special attribute can be set in order to calculate bounding volume of the shape.
Property Documentation▲
boundingVolumePositionAttribute : Qt3DRender::QAttribute*▲
Holds the attribute used to compute the bounding volume. The bounding volume is used internally for picking and view frustum culling.
If unspecified, the system will look for the attribute using the name returned by QAttribute::defaultPositionAttributeName.
Access functions:
-
*boundingVolumePositionAttribute() const
-
void setBoundingVolumePositionAttribute( *boundingVolumePositionAttribute)
Notifier signal:
-
void boundingVolumePositionAttributeChanged( *boundingVolumePositionAttribute)
